Answer: The percentage change is 21.75%.
Let's see how we can calculate this percentage: what is the percentage increase/decrease from 639 to 778? Here is a very simple step-by-step guide to find out.
Step 1: We use the following formula:
\(\text{Percentage change}\) = \({Y-X \over X} \cdot 100\%\)
• \(X = 639\)
• \(Y = 778\)
• Percentage change calculation = \({778-639 \over 639}\) = \({139 \over 639}\) = \(0.21752738654147\)
• \(X = 639\)
• \(Y = 778\)
• Percentage change calculation = \({778-639 \over 639}\) = \({139 \over 639}\) = \(0.21752738654147\)
Step 2: A percentage is a number or ratio expressed as a fraction of 100.
\(0.2175\) = \(21.75 \over 100 \) = \(21.75\%\)
